"In the war of the flea, parliamentary cannonades wreak more havoc than artillery; headlines burst bigger than bombs; peace marches win battles where machine guns fail. Casualties are low because guerrillas, while fighting campaigns of attrition, shun the battles of attrition common to regular armies. Terrorism, conventionally viewed with pious horror as political murder (but how much more murderous than blockbusting a city or napalming a village?) is far more humane, being more selective, than most other types of warfare."
The War Of The Flea by Robert Taber, 1965.
